I am after a visual query builder along the lines of http://ajax.easyquerydemo.com/. I am using ASP.NET but MVC so would rather something that is not WebForms based like the one in the link. If anyone knows of similar tools that are largely platform agnostic please let me know.
Was looking for the same sort of thing, came across this http://devtools.korzh.com/query-builder-component/ which looks very interesting to me...
